If you're having a bit of trouble starting a campfire alcohol-based hand sanitizer gel can help your match or lighter flame catch your tinder on fire. Depending on their alcohol content and type a dime-sized blob of hand sanitizer gel will burn for a minute or two.

Emergency preparedness weblog The Modern Survivalist's YouTube channel demonstrates how well alcohol-based hand sanitizer burns in the video above. Having your tinder burn for a minute longer than it normally would with just the flame of a match can help dry out damp wood and ensure a successful fire. I'm not sure if it will help get your grill's charcoal briquettes ignite, but if you have no other safe fire starting aids on hand it's worth a try.
